POLAR ICEBREAKER CRUISE REPORT GUIDE (RCS-G-NIO-15157)
GENERAL. Cruise Reports should contain complete and essential facts of an icebreaker's
experience during a deployment. The primary considerations should be the usefulness of the
report for planning future icebreaker missions and as historical data for program management.
These reports are also a source for learning ice seamanship. Brevity and clarity in all matters
are necessary if the information is to be valuable to any ice operations reference library. To
this end, the following guidelines apply:
Emphasize ice operations and seamanship, ice-breaking techniques, safety, efficiency,
Report pertinent information on all significant events. Except as otherwise noted,
routine operations, procedures and preparations should NOT be reported. For instance,
the daily inspection of food handlers or the occurrence of routine maintenance should
not be reported.
Times and dates will be listed in local time (including time zone identification), except
where otherwise noted or where another time zone reference is pertinent.
Unique methods of accomplishing assignments are of special interest.
Recommendations for improving operations and specific means of accomplishing
recommended actions are encouraged. Record any information which may be useful to
other icebreakers during similar deployments when such information is not routinely
Detailed information on ports infrequently visited or for which conditions are different
from any previously noted should be mentioned (approaches, moorings, anchorages,
When applicable, reference should be made to directives or previous Cruise Reports
containing information useful in a given set of circumstances or areas of operation.
Names of geographic locations or features should be identified accurately.
Graphic and pictorial information should be employed to the extent that it enhances the
reader's understanding of a particular mission or event.
Completed Cruise Reports should be placed in suitable protective binders and
conspicuously titled or labeled.
In those instances where classified information is reported, all classified information
shall be placed in a separate classified supplement.
